Kilojoule is a unit of heat, joule (abbreviated as Joule) is a unit of heat and work in international units, and kilojoule refers to 1000 Joule.

Extended data often use kilojoules to measure the calories contained in food and the calories consumed in a certain exercise unit time. People generally control their weight by controlling the calorie intake of food and exercise.

Joule (referred to as coke for short) is the derived unit of energy, work or heat in the international system of units, with the symbol J. In classical mechanics, 1 Joule is equal to the energy (or mechanical work) required to exert a force of 1 Newton at a distance of 1 meter. In electromagnetism, 1 Joule is equal to 1 ampere passing 1 ohmic resistance 1 second. Joule was named in memory of physicist James Joule.

Calorie (Cal for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure; Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual. The international standard unit of energy is joule.

Calories, abbreviated as Cal, are defined as the heat required to raise 1 gram of water at 1 atmospheric pressure (10 1.325kPa).

As a unit of measurement for calculating human daily calorie intake, calories are too small, so kilocalories, commonly known as calories (symbol? Kcal, sometimes writing? Cal) as the unit; 1 kcal (1 kcal) is equal to 1000 kcal, that is, 4 186 joules.

Nutritional advice on basal metabolic rate? (BMR), adults absorb 1800 to 2400 kilocalories per day on average. Too much or too little is unhealthy.
